Abstract (en)
A multi-pad electrode (10, 100, 200, 400) comprising a flexible substrate (11) having a multilayer structure printed thereon, is disclosed. The printed multilayer structure comprises: a logic circuit (25, 125, 225); a plurality of switching elements (135, 235) configured for stimulation or recording; and a plurality of electrode pads (40), each electrode pad (40) being in contact with a respective switching element (135, 235). Each switching element (135, 235) is configured to connect the logic circuit (25, 125, 225) to a respective electrode pad (40), the logic circuit (25, 125, 225) being configured to activate or deactivate each electrode pad (40), by controlling propagation of an electrical signal (signal in/out) to each switching element (135, 235) and therefore to each electrode pad (40) or vice versa. A system for electrical stimulation (1) is also disclosed. It comprises: a multi-pad electrode (10, 100, 200, 400); a stimulation/recording device (50), configured to provide stimulating electrical signals to the multi-pad electrode (10, 100, 200, 400), or recording of electrical signals from active electrode pads; and a controller (60) configured to control the propagation of electrical signals from/to the stimulation/recording device (50) to/from the electrode pads (40) of the multi-pad electrode (10, 100, 200, 400).
